Watchdata USBKey

Product introduction

watchdata USBKey is an expert in the field of information security authentication in client identity authentication products.Built-in self-developed high-performance security smart card chip, hardware equipment as the carrier of digital certificates, personal

Authentication keys can be generated in USBKey, and personal keys can not be out of USBKey, using "USBKey"+

The two-factor authentication of PIN code greatly improves the security of personal key.

Application scenarios

Through the USBKey provided by Grip, the authentication certificate key is generated inside the USBKey. Using the SSL protocol between the client and the Web server of the electronic system, an encrypted virtual private channel (VPN) is established between the digital certificate and the authentication center in the USBKey, thus ensuring the security of identity authentication and the security and integrity of data transmission in the electronic system.

Fingerprint Key

Product introduction

Fingerprint Key effectively integrates biometric identification technology with PKI technology, and replaces dense with fingerprint.

Codes are used to authenticate users, which saves the tedious work of memorizing complex passwords, changing passwords and handwritten signatures.

Complex authentication and signature can be accomplished by pressing fingerprint lightly. At the same time, it solves the problems of users and users.

The problem of identity binding between USB Key is that only users who have registered fingerprints can legally use Key to do each one.

Type of authorization operation. 

Application scenarios

Fingerprint USBKey integrates common USBKey, fingerprint identity authentication and other functions, and supports various applications of PKI system. The whole system takes the ARM32 bit embedded processor of the security chip as the core, and uses RSA or algorithm to protect digital certificates and keys stored in USBKey. The whole system runs completely out of the PC environment, thus providing users with top-level data security solutions.

Fingerprint USBKey adds fingerprint image processing and authentication functions to the existing common USBKey products. Besides supporting various applications of the existing WatchSAFE suite, it is compatible with password and fingerprint identification.

Syndrome function.
